Configuration Variables and Values
Configure Pattern Length for
Jitter
RjPattern Short, Long Select "Short Pattern" to have the
DCA measure RJ using Jitter
Mode only to measure, such as
pattern2. Jitter will run faster and
not require a change of pattern or
option 401 or F-AEYE. Select
"Long Pattern" if you are going to
be running a longer pattern than
PRBS15, such as pattern 3. When
selecting "Long Pattern", select
under source for Rj to use option
200 or F-JIT, or a user defined Rj.
Measuring a long pattern requires
option 401 or F-AEYE.
Configure Pattern Verification DisablePattern Enable, Disable Select "Disable" to disable the
pattern verification for square 8
pattern tests and suppress
pattern error pop-ups. Select
"Enable" to ensure that the
correct pattern is being tested as
per specification.
Configure Run Simulation
Signals
RunSim No, Yes Select Yes to run simulation
signals. Set simulation signals to
slot 5 (channels 5A and 5B).
Configure SIRC Bandwidth SIRCBW (Accepts
user-defined text),
33e9, 25e9
Select or enter the SIRC BW. This
will automatically be applied to
any pattern lock waveform.
Configure SIRC Response SIRCResponse BESSel, SINC, FLAT Select the SIRC response. This
will automatically be applied to
any pattern lock waveform.
Configure Samples Taken for
Eye Mode
EyeSamples (Accepts
user-defined text),
150e3, 250e3,
500e3, 1e6, 2e6
Select or enter how many
samples are collected before
calculating eye measurement
results. Default is 250,000
samples. The range of allowable
values is 100K to 2M samples.
Configure Save Tested
Waveforms
SaveWFM No, Yes Select Yes to save the waveform
files of the tested signals. Files
will be saved to directory set in
Select waveform directory.
Configure Select Waveform
Directory
DirWFM (Accepts
user-defined text),
C:\Temp\KRwfm
Type in a directory path to save
your measured waveforms.
